hi, in our unit we do not use diuretics routinely, as we tend to extubate early and use bubble nasal c.p.a.p with or without surfactant,selectivly, with lung defence strategy,,anyhow we use diuretics(lasix,then thiazide+spirolactone) only in case of pending h.f or obviouse water retention, wet lung fields,or renal causes, but not aroutine for prevention of c.l.d,i cant see beneficial effect on long of stay or r.o.p or time of respiratory support,thanks alot
